To all whom it may concern: ,7 7

Be it known that I, WVILLIAM B. SMITH, a citizen of the United States,and a resident of Parkesburg, in the county of Chester and State ofPennsylvania, have invented a new and Improved Injector, forLocomotive-Tea ders, of which the following is a full, clear, and exactdescription. v,

r This invention relates to improvements in water'scoops for locomotivetenders, and has for an object to provide an improved arrangement withmeans for actuating these scoops, and for controllingand regulating thewater as it enters and leaves the tender.

Another object of the invention is to provide an improved arrangement ofmeans for filling the water tank of a locomotive tender withoutunnecessary splashing, and while the tender is moving or stationary.

In the accompanying drawings Figure 1 is a side view of a tenderivith anembodiment of the invention applied thereto; Fig. 2 is an enlargeddetailed sectional view through a connection embodying certain featuresof the invention.

Referring to the accompanying drawings by numerals, 1 indicates anordinary track between the rails of which is arranged a tank containingwater adapted to be used in filling the tender 3, whichtender isprovided with a tank 4 of any desired construction, and into whichprojects an overflow pipe 5. Arranged at any convenient point is aninlet pipe 6 which is positioned at a considerable angle, and preferablyhas the upper end turned so as to discharge the water in an inclineddownward direction. nected with the lower endof the overflow pipe 5 is apivotally mounted scoop 8 supported by link 9 pivotallyconnected withbell crank lever 10. The bell crank lever 10 is pivotally mounted at 11to a suitable bracket 12 which also supports the end of scoop 8. Thebell crank lever 10 has pivotally connected therewith at 13 a rod 14having an extension 15. The extension 15 is pivotally connected to aspring pressed rod 16. Rod 16 extends into the air or steam cylinder 17,and is connected to any suitable rorm of piston so that when air orsteam is turned on to cylinder 17 the rod 16 will be moved against theaction of spring 18 and scoop 8 will be elevated. When the cylinder 17is deprived of pressure spring 18 will move the parts in a reversedirection to that just described, and scoop 8 will con- Consequently belowered. As the bell crank lever 10 Vmoves for raising and loweringscoop 8 the same will operate connecting rod 40, which rod is connectedwith the double lever .19 mounted on bracket 21, whereby the scoop 23will also be raised and lowered. The lower end of lever 19 is pivotallyconnected to scoop 23. Scoop 23 may be of any suitable type provided thesame is journaled in a suitable casing 24 which is supported bybracket'25. The brackets or members 12 and 25 are secured to the tender3 in any desired manner, as for instance by being bolted thereto. By thearrangement of the rod 14 and associated parts the scoops 8 and 23 willbe simultaneously raised and lowered so that the same may act together.

Bolted or otherwise rigidly secured to the casing 24 is acasting 26which is provided with a plurality of apertured members 27 which act assteam jets and with one or more jets 28 for discharging compressed airinto the casting 26. Suitable pipes 29 are connected with jets 27 and apipe 30 is connected with jets 28. The pipes 29 are all connected with asteam supply pipe 31 which is provided with a controlling valve 32operated by a suitable mechanism 33, which mechanism may extend to theengineers cab or any convenient point for easy operation. l/Vhen thesteam is turned on to the pipes '29 the same will be discharged by ets27 into casting 26. These jets extend in a :general upward direction andconsequently will produce a suction or rarefaction in the scoop 23,whereby water will be drawn therein when the tender is stationary, andwill be forced upwardly through pipe 6 and discharged into tank 4.lVhile the tender is moving the water will naturally enter scoop 23' andthe steam jets will force the water.

up into the tank. In case there is not suiiicient power from the steamjets compressed air may be supplied from the air tank 34 for raising thewater. Valve 35 for releasing the compressed air may be operated bysuitable connecting mechanism 36, which mechanism may extend to anysuitable point. It will be noticed that the casting 26 is provided withflanges 38 and 38 so as to be bolted respectively to the casing 24 andto the lower end of pipe 6, as shown in Fig. 1. This section will alsobe easily applied and removed at any time without disturbing the otherparts of the-device. It will be evident that steam may be supis anappreciable'distance from the inlet' pipe 6, and that the inlet pipe 6is at an appreciable angle so that the water Will not be unduly splashedor agitated as thesame enters tank 4. A suitable manhole or entrancemember 39 may be provided if desired, the same being normally closed bya suitable cap or cover. The arrangement of the inlet pipe 6 at an angleallows the water to be forced into the tank 4with a less amount ofenergy so that water may be taken on at comparatively slow speed as wellas high speed. By the arrangement of the steam and air jets water may betaken on while the tender is standing still. From these variousarrangements it is evident that under any and all circumstances watermay be freely taken on by operating certain parts as heretoforedescribed.

WVhat I claim is 1. In a device of the character described,

. the combination with a tank, of an inlet pipe therefor, a pivotallymounted scoop arranged at the lower end of said inlet pipe, power meansfor raising and lowering said scoop, and jets arranged to discharge intosaid inlet member, said jets being adapted to guide gaseous matter underpressure into said inlet pipe for raising the water entering said scoopand discharging the same out of the upper end of said inlet pipe.

2. In a device of the character described, an inlet pipe arranged at anappreciable angle to the horizontal, a movable scoop arranged at'thelower end of said entrance pipe, a'plurality of jets for guiding gaseousmatter into said inlet pipe, means for sup-.

plying gaseous matter to said jets, and valve mechanism for controllingthe gaseous matter supplied to said jets.

r 3. In a device of the character described an inlet pipe, a pivotallymounted scoop, means for raising and lowering said scoop, a tubularmember arranged between said scoop and said inlet pipe and connectingsaid scoop and said pipe, said tubular member beingformed with aplurality of apertured projections extending inwardly, whereby thegaseous matter passing through said jetswill force Water upwardlythrough said inlet pipe, and means for supplying gaseous matter to saidjets.

4. In a device of the character described, an'inlet pipe, a plurality ofsteam jets arranged adjacent the lower end thereof for elevating waterin said inlet pipe, a pivot- .allymounted scoop arranged adjacent thelower end of said inlet pipe, and means for raising and lowering saidscoop.

j 5. In a device of the character described, f j

an inlet pipe, a tubular casting arranged at the lower end of said inletpipe, said tubular castingbeing formed with a plurality of jets, meansfor supplying steamto certain of said jets, means for supplying airunder pressure to other of said jets, and a scoop connected with thelower end of said tubular casting.-

6. In a device of the character described, an inlet pipe arranged at anappreciable angle to the horizontal, a scoop associated with said inletpipe, a plurality of jets for guiding gaseous matter'into said inletpipe, meanslfor supplying gaseous matter to said jets, a valve mechanismfor controlling the gaseous matter supplied from said jets whereby waterentering said inlet member through said scoop will be moved upwardly bythe gaseous matter passing through said 'ets. J In testimony whereof Ihave signed my name to this specification in the presence-of twosubscribing witnesses.
